This is the second post on Excel speed. The first part benchmarked the calculation speed of Excel 2003 versus Excel 2007 for various size arrays of formulas.

#### Power Management: An Animated Buck Switching Regulator Model in Excel 2003

This is an animated model of a Buck voltage switching regulator in MS Excel 2003.

This post considers several aspects about improving the speed of spreadsheets in both MS Excel 2003 and 2007.

#### A Gated Ring Oscillator Demo – Part#2

This is an upgrade from the first part in the sense that it can be adjusted to have more delay based inverters in the feedback (14).

#### A Gated Ring Oscillator Demo – Part#1

An interactive animated demo of the gated ring oscillator in Excel 2003 based on the previous tutorial. This model stands out because of the real time schematic animation.

#### An Interactive Gated Ring Oscillator Tutorial – part #2

This is the second part of tutorial walking through the creation of an interactive animated Excel model of a gated ring oscillator in MS Excel 2003.

#### An Interactive Gated Ring Oscillator Tutorial – part #1

This is the first part of tutorial explaining how to make an interactive animated Excel model of a gated ring oscillator in MS Excel 2003.

#### A Delay Based Animated Excel Model for Single-Stage Logic Gates – part#2

This is the second half of the delay based Excel model tutorial. In this part the final formulas are derived and implemented in Excel 2003.

#### A Delay Based Animated Excel Model for Single-Stage Logic Gates – part#1

After learning how to model ideal logic gates in MS Excel 2003 it is time to attemp to create a delay based model.

#### Introduction to Digital Electronics – a Simplified Model for Logic Gates – part#3

This is the third part of a tutorial about modeling logic gates in MS Excel 2003. This first model includes no delay or loading for the gates.

#### Introduction to Digital Electronics – a Simplified Model for Logic Gates – part#2

This is the second part of a tutorial targeted at modeling logic gates in MS Excel 2003.

#### Introduction to Digital Electronics – a Simplified Model for Logic Gates – part#1

This is the first part of a tutorial (self, 2, 3) about modeling logic gates in MS Excel 2003. This first model will include no delay or loading for the gates.

#### An Animated Linear Feedback Shift Register (LFSR) as a Pseudo Random Pattern Generator in Excel 2003 – Part#4

This is not a tutorial but a download post for a purely animated Pseudo Random Number Generator model as a Fibonacci type Linear Feedback Shift Register in MS Excel 2003.

#### An Animated Linear Feedback Shift Register (LFSR) as a Pseudo Random Pattern Generator in Excel 2003 – Part#3

This is the third part of a tutorial (1, 2, self) describing the creation of an animated Pseudo Random Number Generator model as a Fibonacci type Linear Feedback Shift Register in MS Excel 2003.

#### An Animated Linear Feedback Shift Register (LFSR) as a Pseudo Random Pattern Generator in Excel 2003 – Part#2

This is the second part of a tutorial (1, self, 3) describing the creation of an animated Pseudo Random Number Generator model as a Fibonacci type Linear Feedback Shift Register in MS Excel 2003. This part creates a very simple table type model based on combinatorial logic rather than a sequential type based on registers.
